Answer:

F: independent: speed; dependent: fine

your fine depends on the speed over the speed limit.

G: independent: pots; dependent: flowers

you already bought the pots. the amount of flowers you buy depends on how many pots you have.

H: independent: time; dependent: length

the time spent knitting is up to the grandmother. the length depends on the time spent knitting.

I: independent: cars washed; dependent: money made

the money you make depends on the amount of cars you wash

Answer:

see below

Step-by-step explanation:

The independent variable is the variable that gets changed and the dependent variable relies on the independent variable

F.If you get pulled over for speeding, the ticket will cost $50 for each mile over the speed limit.

The independent variable is the miles over the speed limit, and the dependent is the cost

The cost relies on the number of miles over the speed limit

G.You are starting a garden and already bought the pots for $25.

Each flower you buy costs $3.50

The independent is the number of flowers purchased, the total cost is the dependent

The cost is dependent on the number of flowers purchased

H.Your grandmother is knitting you a blanket. She already made the blanket 5 inches long. Each hour she knits, the blanket gets 0.8 inches longer.

The independent is the hours knitted, the dependent is the length of the blanket

The length will depend on how long she knits

I.You are washing cars for a fundraiser. You make$10 for each car washed.

The number of cars is the independent variable and the dependent variable is how much money you make

How much  you make depends on how many cars you wash

Answer:

17c + 18

Step-by-step explanation:

Distributive property: a(b + c) =a*b +a*c

8c + 9(c +2) = 8c + 9*c + 9*2    {Distributive property}

                    = 8c + 9c + 18  

Combine like terms, her 8c & 9c are like terms

                      = 17c + 18

Answer:

Step-by-step explanation:

Answer:

An expression for the area of the rectangle if the width is w inches is

[tex]A =[/tex] 3w

when the width is 1 inch, Area = 3 square inches (in²)

when the width is 2 inches, Area = 6 square inches (in²)

when the width is 3 inches, Area = 9 square inches (in²)

when the width is 26 inches, Area = 78 square inches (in²)

Step-by-step explanation:

The area of a rectangle is given by

[tex]A = l[/tex] × [tex]w[/tex]

Where [tex]A[/tex] is the area of the rectangle

[tex]l[/tex] is the length of the rectangle

and [tex]w[/tex] is the width of the rectangle

From the question,

length, [tex]l[/tex] = 3 inches

width, [tex]w[/tex] = w inches

Hence, An expression for the area of the rectangle is

[tex]A =[/tex] 3 × w

[tex]A =[/tex] 3w

Now, to find the area of the rectangle when the width is 1, 2 , 3, and 26 inches

1. when the width is 1 inch (That is [tex]w[/tex]  = 1 inch)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 1

[tex]A =[/tex] 3 square inches (in²)

2. when the width is 2 inches (That is [tex]w[/tex]  = 2 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 2

[tex]A =[/tex] 6 square inches (in²)

3. when the width is 3 inches (That is [tex]w[/tex]  = 3 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 3

[tex]A =[/tex] 9 square inches (in²)

4. when the width is 26 inches (That is [tex]w[/tex]  = 26 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 26

[tex]A =[/tex] 78 square inches (in²)

Answer:

[tex]d+0.5c+2r=8\\\\ c=2d[/tex]

Step-by-step explanation:

Let d= dramas

c= comedies

r= reality shows

Dramas are 1 hour long, comedies are 30  minutes, and reality shows are 2 hours long.

Total time spent on watching = [tex]1 \times(d) + 0.5 \times (c) +2 \times(r)= d+0.5c+2r[/tex]

 [  [tex]30\ minutes=\dfrac{30}{60} \ hours = 0.5 hour \ \ (1 hour = 60\ minutes)[/tex]  ]

Since he spent 8 hours for this, that means

[tex]d+0.5c+2r=8[/tex]     → First equation

He watches twice as many comedies as dramas.

i.e. [tex]c=2d[/tex] → second equation

So, the system of equations could be used to determine how many of each type of show he watches each week:

[tex]d+0.5c+2r=8\\\\ c=2d[/tex]

Please give brainliest thanks! Also I quoted it and listed where i took the info so brainly mods. please do not take this down

Parallel lines are always coplanar. Perpendicular lines are always coplanar and, Distance around an unmarked circle can never be measured.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.

1. Parallel lines are always coplanar.

When two lines are parallel to each other it means that the two lines will never intersect each other and their plane is also the same.

2. Perpendicular lines are always coplanar.

From the definition that two lines will be perpendicular to each other their angle should be 90 degrees or they should intersect at 90 degrees angle to each other.

3. Distance around an unmarked circle can never be measured.

We need to have a marked circle to measure the distance. So, the distance from the centre of the circle to one point of it is the radius. Moreover, the distance between two points of the circle taking a line passing through the centre is the diameter of the circle.

Answer:

b. $1584.52

Step-by-step explanation:

To find the answer, first you have to find the amount that you will have after 9 years using the formula to calculate the future value:

F=P*(1+i)^n, where

F= future value

P= present value= $2874

i= interest rate= 5%

n= number of periods of time= 9

Now, you can replace the values in the formula:

F=2874*(1.05)^9

F= 4458.52

Then, as you know the value that you will have after 9 years, you can subtract the initial balance from this, to find the amount of interest:

$4,458.52-$2,874= $1,584.52

According to this, the answer is that the amount of interest at 5% compounded annually would be $1,584.52.

A vertical line has undefined slope.

The equation of a vertical line is x = b, where b is the x-coordinate of all points on the line.

We are told the line contains point (7, 2) with x-coordinate 7, so all points on this line have x-coordinate 7, and the equation of the line is

Answer:

14,100.03 (just finished a test with this question and got it correct)

The car is worth about $14,100.03 after the second year.

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

If a car depreciates at a rate of 24.9% annually, then its value at the end of each year is 75.1% of its value at the beginning of the year (100% - 24.9% = 75.1%).

After the first year, the car's value is:

$25,000 × 0.751 = $18,775.00

After the second year, the car's value is:

$18,775.00 × 0.751 = $14,100.03

Therefore, after the second year, the car is worth about $14,100.03.
